If you’re late to an appointment or about to meet your new boss, the reason for your Anxiety is pretty obvious, but if you feel nervous, worried, and even panicked for no reason, a number of surprising daily habits may be responsible.

You’re ThirstyIf you’re not drinking enough water, you’re going to have more than just a parched mouth. Even mild dehydration can trigger disturbances in mood, according to a study in the Journal of Nutrition.

It’s important to stay hydrated by drinking water at meals and throughout the day to prevent feeling off-balanced. As a bonus, drinking more water may help you shed pounds.

You Drank A Lot Of CoffeeWhile you may think nothing of that extra cup of coffee, but the fact is caffeine makes the body nervous and jittery, and triggers the fight or flight response. According to a study from the British Journal of Psychiatry, taking too much coffee has been shown to produce symptoms that are indistinguishable from anxiety disorder.

You Have A HangoverAccording to research from University of North Carolina School of Medicine, a pounding headache and nausea aren’t the only after-effects of drinking too much. Excess alcohol is one of the main triggers of anxiety, as heavy drinking can rewire the brain and make you more susceptible to anxiety disorders.

Alcohol is also known to disrupt your sleep, and sleep deprivation can boost your anxiety levels, according to research from UC Berkeley.

You’ve taken MedicineIf you’re sick and wondering to yourself, “Why do I feel anxious?” It may be the over-the-counter medication you took a night before.

It’s important to read ingredients, because drugs like acetaminophen, doxylamine succinate, which is a sedating antihistamine, and dextromethorphan, a cough suppressant, all can trigger anxiety and a general on-edge feeling.

Your Blood Sugar Is LowWe’ve all heard that you can get “hangry” from not eating (that’s an unfortunate blend of hungry and angry), but you can also feel anxious as well. People who are under stress and have anxiety often feel that their appetite shuts down.

Skipping meals leads to a drop in blood sugar, which only keeps the anxious feelings going, creating a vicious cycle. Even if you’re not up for a full meal, keep your blood sugar steady with healthy snacks.
